    Abstract:
    AIM: To compare the esophagogastric junction (EGJ) areas observed in sedated and non-sedated patients during esophagogastroduodenoscopy (EGD). METHODS: Data were collected prospectively from consecutive patients who underwent EGD for various reasons. The patients were divided into three groups according to the sedation used: propofol, midazolam, and control (no sedation). The EGJ was observed during both insertion and withdrawal of the endoscope. The extent of the EGJ territory observed was classified as excellent, good, fair, or poor. In addition, the time the EGJ was observed was estimated. RESULTS: The study included 103 patients (50 males; mean age 58.44 ± 10.3 years). An excellent observation was achieved less often in the propofol and midazolam groups than in the controls (27.3%, 28.6% and 91.4%, respectively, P < 0.001). There was a significant difference in the time at which EGJ was observed among the groups (propofol 20.7 ± 11.7 s vs midazolam 16.3 ± 7.3 s vs control 11.6 ± 5.8 s, P < 0.001). Multivariate analysis showed that sedation use was the only independent risk factor for impaired EGJ evaluation (propofol, OR = 24.4, P < 0.001; midazolam, OR = 25.3, P < 0.001). Hiccoughing was more frequent in the midazolam group (propofol 9% vs midazolam 25.7% vs control 0%, P = 0.002), while hypoxia (SaO2 < 90%) tended to occur more often in the propofol group (propofol 6.1% vs midazolam 0% vs control 0%, P = 0.101). CONCLUSION: Sedation during EGD has a negative effect on evaluation of the EGJ.
